WebJul 14, 2024 · The diagram below shows that pepsin functions best in an acid environment. This makes sense because pepsin is an enzyme that is normally found in the stomach where the pH is low due to the presence of hydrochloric acid. Trypsin is found in the duodenum, and therefore, its optimum pH is in the neutral range to match the pH of the duodenum. WebThe digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). In the intestine the gastric acids are neutralized (pH 7), and pepsin is no longer effective. … WebExplains that low and high ph levels results in inactivity of enzymes. if it is too acidic or too basic it has the same effect in loss of activity. Explains how an enzyme affects the energy of a reaction, but not the free energy. enzymes work by decreasing the activation energy, so the product's energy is the same as it would be without the enzyme. how chechnya became muslim
